stapled wool or similar material.

dle or comb segment 2 mounted "on a main The'machines of this type in common use are open :to the objection'that they are relatively complicated in construction, have a comparatively small output,-are very noisy in operation, and-depreciate rapidly. It is, the chief object of the present inventionlto overcome these objections; In other words,

the invention aims to devise amachine'of" this typewhich will be simpler in construc= tion than prior machines, more eco omical? I v e v I the manner'above descr bed, movement Wlll to build, will be smoother inoperation, and willhave an increased capacity.

The nature of the invention will be readily vunderstood from the following description when read-in connection with the a'ccompanying drawings, and the novel features will be particularly pointed out in the appendedclaims. Referring now to the drawings, Figural is a side elevation of the more important parts of a combing machine constructed in accordan'cewith this invention;

Fig. 2 is a view similar to Fig. 1 showing. the parts in a different position; and j i Fig. 3 is another view showing the manner in which the material is handled at one point in the cycle ofthe operation ofthe machine, i

The construction shown comprises 'a nee shaft 3 supported in suitable; bearings. Keyedto this'shaft is an eccentric 1; which drives an eccentric'strap 5 'having'an arm shown in anot r This'me'c thedetachingrolls" atany desired speed.' It

" spring 17 secured to'itsre'arward end which acts normally to hold the, lower nipper in contact with the upperlnipper. It will be apparent that the entire'nipper mechanism is swung back and forward by the eccentr1c4.

The" machine also" includes detaching mechanism"comprising fluted rolls 20 and 21 'mountedona lever or arm 22 which is so cured to a rock shaft-'23. Fast on this rock shaft 23 is an 211711124 having a long slot 25 therein. "This arm overlaps a link 26, pm, oted to therearward' arm 27 of the bell crank. lever? previously referred to. The connection between the parts 24and 26 includes a two parts canbe adjusted;

b It will'now teappreeiat d that as the co centric 4- rotates, thus moving the arm 6 up and "down and-swinging the nippe'r frame in also be transmitted through the parts 27,] 26'and24 toflthe detaching frame 22, oscil lating this frame backward and forward about the axis of theshaft 23. 1 v

The detaching rolls 20 and 21 are geared t0gether,j-the gea'roiithe loweigroll 21 being w Fig. 1 at '30.; This gear meshes with another gear 31, driven by a gear 32 which rotates" on'the' shaft 23 andis'driven' byachangegear 33 mounted on a shaft 34:; Thefsh aft 34c is "driven bya" gear 35 from' ear-36 "fast on the mainshaft lianism thus "permits the driving of should be noted also that due to the back, ward and forward movement of y the detachin}; frame or' leve'r22, the rolls 20 and 21 are rotated atla variable'rate'.

The fwool or other material to' be combed is led through" the chute 38 and under the feed roll 39 to a 'point'between the nippers 12 ailil'l. During the operation of the mabolt orstud 28 which passes through the,

i 6 projecting upwardly'therefrom. This arm has a bolt and slot connection with one arm 7 of a bell crank lever secured fast to the rock shaft 8 by means of a set screw 9. The nipper'f'rame is mounted fast'on this shaft and comprises 'a lever 10, to the forward end of whichthe upper nipper 12 is secured. The lowernipper"'14c"'is mounted on the forward arm of a lever15- which isfulcrume'd on-a stud 16 carried by the ni per lever 10, thelever 15 having a long hereal "chine the jtu ft or length ,of materialprojecting-from betweenithenippers is combed by the teeth on the comb segment 2. As the eccentric-2t rotates in the directionfindicated by the arrow, Fig; 1, and the nipper frame andthe detacherj frameswing toward each other, the nippers bring the combed mater al 'intodeliverin positiomas shown in, Flg.

2, where the detaching rolls 20 and 21,: en-' gageeaid material. Just before the mp'perJ frame' 'reachesflthe" position in which it 15 the opposite shown in Fig. 2, the set screw 4:2 on the lever- 15 engages a stop 43 and preventsthe lower nipper 14 from following the upper nipper any further, the continued movement of the lever 7 carrying the upper nipper away from the lower nipper, and thus opening the nippers. As the rolls start to swing backwardly they draw the combed material through the nipper frame thus performing the detaching operation. During this ope-ration they also pull the stock throughthe upper comb 4E1. -This comb is moved into and out of combing position by means of connections with theshaft or stud 16 carried by the nipper lever 10.

The nipper mechanism and I detaching.

mechanism pause for only an. instant the position shown in Fig, 2 and immediately start to swing away from each other again.

The nippers again nip the stock, a new length of which hasbeen pulled through them, and they swing slowly backward tov their initial positions, as shown in :Fig. 1,

the new tuft of uncombed material project-f ing in front of the nippers being partially combed during this backward movement. This combing operation is completed before the stock is presented to the detaching rolls when the nipper frame is again swung in direction. It will be observed that the long teeth of the, comb segment first engage the tuft of material to be combed and perform the primary combing operation, while the shorter teeth later engage this tuft of material and subject it to a very gentle secondary combing.

7 As the detaching rolls are swung toward the nipper frame the partof the web which hangs down behind the rolls is brought against the side of the web Dan 45,- as best shown in Fig. 2, the end of the newly delivered tuft being laid upon the upper part of this portion of the web. The overlapping effected in this manner results in producing a very uniform web detaching roll by additional rolls lG and 47.

which pull it through the funnel 48, thus forming a sliver which drops intoa coiler, as usual in machines of this type.

Attention is particularly called to the fact that the swinging movement of the nipper mechanism may be adjusted through the bolt and slot connection between the eccentric and the lever 7. Likewise the swinging be adjusted independently of the movement of the nipper frame by adjusting the stud 28 in the slot: 25 The speed of rotation of the nipper rolls also can be adjusted to suit existing conditions by changingthe gear 33, as has been mentioned above. The fact that the swinging movement ofboth the nipper and detaching mechanism is produced by a movement of the detaching mechanism.may.

single driving member, namely, the eccem of combed material.

trio 4, provides a very simple construction and enables the mac ine to operate very smoothly. This reduces the depreciation and the necessity for repairs. At the same time the nature of the driving mechanisms for the nipper and detaching frames and the detaching rolls substantially increases the output of the machine.

While I have herein shown and described the best embodiment of the invention of which I am at present aware, it will be ap preciated that this embodiment may be modified in many particulars without departing from the spirit or scope of this invention.
